s88-Power

3.2. Connection to the s88 bus

In order to connect the module s88-Power to the s88 bus you use Ethernet patch cables with
RJ-45 connectors.
! Please note:
Do not use the s88-Power together with s88 modules with RJ 45 connections that do not
comply with the s88-N standard! The s88-Power and s88 modules connected to the bus can
be damaged.
Connect the two Ethernet-cables according to the
connection diagram to the RJ 45 connection sockets.

Interface (→ Interface / digital control unit)

Power (→ s88 modules to be supplied)
Observe the correct assignment of the cables to the two
sockets.
! Please note:
An interchanged connection of the two Ethernet-cables to
the sockets "Interface" and "Power" possibly causes
serious damage to s88-Power and other current suppliers
connected to the bus line. In case you discover a wrong
connection, disconnect the power supply for the s88-
Power module immediately!

3.3. Connection to the voltage supply

As a voltage source you can use a power pack with

12 V a.c. voltage (~) or

12 – 18 V d.c. voltage (–)
in each case with a current of at least 800 mA.
The connection of the power pack to s88-Power is made via a coaxial (DC) power connector
5.5 / 2.1 mm (outer / inner diameter).
! Attention:
Do not use a power pack with a higher nominal voltage than specified. The resulting surplus
power has to be dissipated as heat by s88-Power. There is a risk of fire if the nominal
voltage of the power pack is too high!

3.4. Displaying operational readiness

As soon as the LED between the two RJ 45 sockets lights up brightly, voltage is present and
the s88-Power is ready for operation. If the LED is only dimly lit, the power supply to the s88-
Power is interrupted (e.g. the power supply unit is de-energised).
